Brunette beauty Kendall took the opportunity to make a joke about Kourtney's height, and posted a snap of two brunettes (we can't decide if it is actually them, probably not), with writing saying: "I can't stand next to you when you're that tall. No, it's ridiculous."

Kylie sent a much longer writeen message with a snap of her and her sister all dolled up on a night out and wrote: "#fbf @kourtneykardash I still hate you for not letting mom buy me that tinker bell nightgown at Disney world but I guess I can forget about it today. Happy birthday I love you."

Keen to make sure the sisters didn't out-do him, Scott Disick then took to Instagram and posted a lovely snap of them together.

The pair appear to be sat on a plane together, with a very tanned Kourt smiling happily next to her man.

Scott wrote: "Happy birthday @kourtneykardash."

The whole family enjoyed some early Easter celebrations yesterday all thanks to momager Kris Jenner and her amazing colourful chocolate skills.
